btw sir uber, what does the switch do? i guess what im trying to ask is the sound that you could get out of it.

EDIT: I misunderstood your question, so ignore my previous statement.. the toggle switch, switches between the traditional clipping diodes and a MOSFET used as a clipping diode. The MOSFET gives a cleaner, tighter more open sound when compared to the traditional diodes (1N4148). It also clips the signal more asymmetrically. To my ears, the 1N4148 diodes sounds a little fuzzy and loose, kinda squishy. The level also increases with the MOSFET.
